Andy Serkis cast in Avengers: Age of Ultron

Motion capture star working closely with Mark Ruffalo

Having already signed on to appear in Star Wars: Episode VII, Andy Serkis will add another mega-franchise to his CV by taking on a role in Avengers: Age Of Ultron .

"The Imaginarium (Serkis' production company) is the performance-capture consultant, and I’m playing a role," confirms Serkis. "On The Avengers , I’ve been working closely with Mark Ruffalo."

"Performance capture was used on the previous Hulk, but not to the same extent Mark is using it now," explains Serkis.

"There are tools and ways of working with an actor that makes them feel that they own the character. And a character the size of the Hulk needs ownership, which Mark has now."

And as to his own character, will this be another performance-capture role, or will Serkis actually get his face on screen?

"I’m not at liberty to mention," says Serkis. "But it’s all the same to me. I’ve never drawn a distinction when playing a role, whether it be live action or performance-capture. Acting is acting. It’s just basically what you wear to the set that’s different."
